When testing the serving BSS part of the RIM application in osmo-pcu, we
will need receiving templates that allow us to verify the response (RAN
INFORMATION) rim container.

The gbproxy tests and our scripts have started to use
hdlc0..7 paired with hdlcnet0..7. Let's adjust fr-net to
also use 'hdlcnet1' as the pairing 'fr' test uses 'hdlc1'

Sending a message [even over a real or simulated E1 line] should always
be less than 1s end-to-end. But just to see if increasing the timeouts
to 2s will result in less test failures, let's change from 1s to 2s.

Allow ignoring for received dumy packets while waiting for a Pkt Ass on
PACCH. This fixes some tests failing sometimes due to race condition
where rlcmac packet is requested too quicky, after the PCU has received
the BSSGP packet we sent to it.
The function is splitted into an internal altestep + a wrap function
which is compatible with tests already using it.

This feature is useful in simulating intermittent or permanent transport network
outage by simply halting processing of all rx+tx in the specified NS-VC
until it is administratively re-enabled.

With pooling enabled these tests now need to verify that the reset/block

As we know, many production deployments have SGSN architectures with
clear control / user plane split. In such situations, IP-SNS of the
SGSN informs us of two (classes of) IP endpoints:
some that have control_weight > 0 and data_weight 0
some that have control_weight 0 and data_weight > 0
Let's adjust the GBProxy_Tests.ttcn to use such a configuration for
each of the two simulated SGSNs.

* allow configuration of signalling + data weight for each NS-VC
* advertise per-NSVC signalling/data weight in SNS-CONFIG
* keep track of unblocked NS-VCS separately for data / signalling
* transmit BVCI=0 traffic only over signalling NS-VC
* transmit BVCI>0 traffic only over data NS-VC
* accept incoming BVCI=0 traffic only if signalling_weight > 0
* accept incoming BVCI>0 traffic only if data_weight > 0

We need to move the IP-SNS handling up one layer, as only the NS-VCG
knows all the other NS-VCs, and after the SNS-CONFIG-ACK, we must
mark all of our NS-VCs as alive and start the alive procedure.

The ConnHdlr test stores the sgsn_idx in g_pars. Use that in the paging

Previous RAW_NS only supported NS over UDP because
it handled the UDP connection on it's own.
Because of this there was no cleanup function for the tests
because no virtual component were started.
Using the new NS_Provider allows to use the same tests over
UDP and FR with no changes.

We change the osmo-gbproxy.cfg to use NRI 3 for SGSN-0 (NSEI 101) and
NRI 4 for SGSN-1 (NSEI 102).
We also add the capability to GBProxy_Tests to allocate P-TMSI with
a specific NRI and default to the first NRI of SGSN-0 so all tests
written still for a single-SGSN-non-pool scenario pass without any
modification.
